I am trying to delete multiple rows from a table.
In regular SQL Server, this would be simple as this:
DELETE FROM Table WHERE Table.Column = 'SomeRandomValue' AND Table.Column2 = 'AnotherRandomValue'
In Entity Framework 6, they have introduced RemoveRange() method.
However, when I use it, rather than deleting rows using the where clauses that I provided, Entity Framework queries the database to get all rows that match the where clauses and delete them one by one using their primary keys.
Is this the current limitation of EntityFramework?
Or am I using
Following is how I am using
db.Tables.RemoveRange( db.Tables .Where(_ => _.Column == 'SomeRandomValue' && _.Column2 == 'AnotherRandomValue') );
What you are looking for is a Batch Delete Library which deletes multiple records in a database from a LINQ Query without loading entities.
Multiple libraries supporting this feature exist.
You can find the list here: Entity Framework Batch Delete Library
Disclaimer: I'm the owner of the project Entity Framework Plus
// using Z.EntityFramework.Plus; // Don't forget to include this. // DELETE directly in SQL (without loading entities) db.Tables.Where(_ => _.Column == 'SomeRandomValue' && _.Column2 == 'AnotherRandomValue') .Delete(); // DELETE using a BatchSize db.Tables.Where(_ => _.Column == 'SomeRandomValue' && _.Column2 == 'AnotherRandomValue') .Delete(x => x.BatchSize = 1000);
